Embodiment 1
[0016] Embodiment 1: multi-component ceramics Composition: kaolin 13%, clay 3%, quartz 2%, feldspar about 6%, zirconia 5%, alumina 55%, zirconium silicate 16%.
[0017] The first choice is to divide the materials into one group according to the difference of the Mohs hardness value of the raw material within 2, kaolin, clay, quartz, feldspar and ceramic auxiliary materials are group A, alumina is group B, zirconium silicate and zirconia are group C;
[0018] Next, add a total of 5 tons of raw materials in Group A to a 5T ball mill for grinding for 10 hours, add a total of 11 tons of raw materials in Group B to a 10t ball mill for grinding for 25 hours, and add a total of 4.2 tons of raw materials in Group C to another 5T ball mill for grinding for 18 hours so that the median particle size of the output reaches 1μm or so, and finally put the group-ground slurry into the mixing tank in proportion to mix;
[0019] Finally, all raw materials are mixed and ground, and the median di...

The invention relates to an efficient ultrafine grinding method and grinding system of multi-component ceramic powder materials. Powder materials with different hardness are respectively subjected topre-grinding treatment, so that ultrafine particle sizes can be quickly achieved; and then slurry with a relatively uniform particle size is obtained through mixing, stirring and homogenizing. The system is composed of ball mills, a stirring homogenizing tank and other auxiliary devices. Differences between the ceramic raw materials in initial fineness and hardness are fully considered; the materials with different wear resistance are independently ground by the ball mills for production; then slurry is conveyed into the homogenizing tank through a pipeline; and different powder materials canbe uniformly mixed through an outward-turning downward-pressing type stirring mode. According to the system, mutual influence of materials with different hardness during the grinding treatment is avoided, so that the grinding efficiency is improved, the grinding time and the grinding energy consumption are reduced, meanwhile, the uniformity of the particle size of the powder materials is ensured,and the product performance is improved.
Description
technical field [0001] The invention relates to ceramic powder grinding technology, in particular to superfine and efficient grinding of multi-component ceramic powder. Background technique [0002] At present, the method adopted by the ceramic industry for large-scale grinding of multi-component ceramic powder is generally to use a ball mill to grind for 20~55 hours. The median particle size of the ceramic slurry is about 1.6. When the powder contains more hard materials There are coarse particles in the medium, and the particle size is uneven. The data shows that when the median particle size of the material in the ball mill is less than 1 μm, the grinding efficiency decreases rapidly as the particle size becomes finer. Increasing the grinding time will lead to an increase in unit production cost. Secondly, when the multi-component material contains more viscous materials It will also lead to a reduction in the grinding efficiency of the ball mill. [0003] At present, t...
